Alligators are nesting, and we are at the end of alligator mating season. Alligator courtship begins in early April, and mating occurs in May or June. You might have heard some sounds you are unfamiliar with, and it could have been the alligators mating, as they are noisy. Males are the showiest of the species and they interest their mate by head slapping, vibrating their torso, bellowing, and jaw slapping. The females join in by making a sound more like a growl, but without the fanfare of the showy male. In the animal world, alligator courtship is lengthy, often extending 6-8 weeks with copulation occurring underwater quite a few times during courtship. Interesting fact: males and females may have multiple partners during a courting season and a single clutch of eggs may have multiple paternities.
By June, the female seeks the right location to build her nest. The female piles vegetation and compresses the materials she has gathered and diligently builds her nest. It can take a few days, or upwards of a month for the nest mound to be built. Once the female is satisfied with the nest, she climbs on to the mound and spends several hours slowly turning to make a depression on the top. She then deposits 20 to 50 oval eggs. The female returns to the water's edge numerous times to gather muddy vegetation to pile on the depression. The incubation period is 65 days. As the alligator embryos develop, it is the heat in the nest that will determine the sex of a baby gator. A temperature of 91 degrees or higher produces a male, a temperature of 86 or below produces a female, and in between the two temps there is a 50-50 chance of either a male or female being born. Lee and I always enjoy getting to know our neighbors; and some facts about the local wildlife too.
